There is nothing scarier or less predictable than a woman scorned. When I went through my divorce, I initiated it and told her there was no chance of reconciliation. Even if that's the case, don't say it or even hint it. Once I told her that and she actually got it (took several times, methods of communicating it and several months) omfg, she was like a monster, nothing like the woman I had originally married. Took me 3 years of fighting her in court to get any sort of reasonable agreement, so glad my kids were on grown and on their own, I'm sure she would have tried to use them against me. She tried everything else...
So my primary advice for anyone going through a divorce is even if it makes you feel like a pussy (think of this as an investment), never completely cut off that possibility of reconciliation (even if you know it'll never happen), keep any dates/girlfriends quiet, in general keep the peace and let her at least believe she's in control (within reason of course, don't be a real pussy, just act like it). Otherwise, you have no fucking idea what that woman scorned saying really means
